Prerequisites

  • - PostgreSQL server configured with SSL enabled.
  • - Appropriate CA/certificate chain files if your setup requires verification.
  • - Application or tool support for SSL modes.

Step-by-step

  1. 1.Confirm server SSL settings and accepted client SSL modes.
  2. 2.Choose the strictest SSL mode your environment supports reliably.
  3. 3.Configure certificate paths when your environment requires custom CA trust.
  4. 4.Test handshake success and validate certificate details in staging first.
  5. 5.Enforce SSL in production connection profiles and monitor for fallback misconfigurations.
